Abstract
Some consequences of the S/P wave problem after the rst measurements o f the branching ratios of two-meson final states in gaseous hydrogen a t various pressures (2 mbar, 5 mbar, 1 atm) performed using the OBELIX apparatus are discussed. In particular, the ppBAR --> pi0pi0 branchin g ratio at 1 atm allows for the determination of the P-wave percentage at that pressure in a way independent from previous methods.
